Question

I am using SQL Server database and after calling a simple SQL script I would like to know how many records were affected by last (or only) executed statement in a script.

I cannot find the reference how to achieve this in Delphi’s TADOCommand and I know SQL Server gives this information to provider. I am aware of workarounds like getting @@ROWCOUNT in another query, yet this gives some overhead and unnecessary complexity.

Thanks.

Answer 1

Do you use the

function Execute(var RecordsAffected: Integer; const Parameters: OleVariant): _Recordset; 

version of the Execute method?

From the doc:

RecordsAffected indicates the number
of records, if the command operates on
data, that are affected by the command
after execution.

So that should give you what you need.

Disclaimer: I cannot test this against SQL Server (don’t have it).
